The device of
A securing device adapted for retaining an elongated workpiece such as a group of cable-like elements in suspension from a support; said device comprising a generally flat member made of flexible plastic material including an elongated relatively thin and narrow strap portion of rectangular cross-section and a head adjacent one end thereof which is transversely thicker than the body of said strap portion substantially throughout the longitudinal extent thereof, a plurality of locking elements integral with and projecting from one surface of said strap portion and spaced longitudinally therealong, said integral locking elements projecting outwardly from the face of said strap portion a distance substantially as great as the, thickness of said strap portion, each of said locking elements presenting a locking shoulder facing toward the head extremity of the strap portion and a cam surface extending in the opposite direction from the outer extremity of the locking shoulder and toward the adjacent strap surface, said relatively thick head portion having a rectangular aperture therethrough disposed adjacent the area of merger between the head and strap portion and conforming substantially with the rectangular cross-section of said strap portion and adapted to accommodate the free extremity of said strap portion to permit lacing of the strap portion therethrough to form a loop for receiving the aforesaid elongated workpiece with sufficient area of the relatively thick head remaining outwardly of the aperture to receive a fastening element for attachment to a support, said head although thicker than the body of the strap portion being sufficiently resilient to flex as an incident to the forced passage of the locking elements through said rectangular aperture but presenting substantially the thickness of the head material to an inserted locking shoulder whereby to assure firm locking abutment of an inserted locking shoulder against the relatively thick head and resist reverse movement of the strap portion under influence of the weight of the assembly when suspended by the head from a support.
A wire or cable bundle tie in the form of a noose slidable one way and selectively clampable against movement the opposite way comprising: a flexible strap having transverse serrations on one face and at one end thereof; and a clamping guide loop with outwardly bowed flexible side walls on the other end thereof, said clamping guide loop being on the same face as said transverse serrations and having a transverse sawtooth tongue depending from the upper inside surface thereof, the vertical portion of said saw-tooth tongue facing the vertical portions of said transverse serrations so that when said one end of said strap is inserted through said guide loop, said vertical portion of said tongue engages the vertical portion of one of said transverse serrations, said flexible side walls of said flexible clamping guide loop being deformable on inward lateral pressure to raise said tongue, thereby releasing said tongue from said serrations to permit removal of said strap from said guide.
An integral one-piece cable tie including an elongated flexible strap having a row of teeth thereon, a frame integral with one end of the strap and having an abutment wall and an end wall and an entry surface and an exit surface and a strap-receiving opening therethrough, a ledge on the end wall extending toward the abutment wall, and a pawl pivotally mounted on and integral with the ledge within the opening end having a set of teeth thereon shaped complementary to the row of teeth.
A releasable ladder fastener for securing elongate objects in a bundle having a stud mount boss for securing the ladder fastener to a stud mount. The releasable ladder fastener includes resilient barbed locking members formed at a first end of the ladder strap that releasably engage the side rails of the ladder fastener strap to releasably lock the first end of the ladder strap to the strap of the ladder fastener.
A restraining method employs apparatus that has a body portion and two, laterally-spaced, downwardly extending flexible straps that can be looped around in opposite directions to be lockingly received by a toothed ratcheting mechanism in corresponding laterally-spaced openings of the body portion. An upwardly extending tab has an opening through which a rope can be strung to link together several restrained prisoners. Strap teeth and tab are located in limb noncontacting positions. The straps bend double about self-hinges with free ends fitting within non-ratcheted loops for pocket storage.
A selectively coated cable tie is only coated along the lateral edges of the strap of the cable tie leaving an uncoated longitudinally extending medial strip portion of the strap for engagement with a locking mechanism in the head of the tie whereby the selectively coated cable tie provides a cable tie with smooth non-abrasive lateral edges while not significantly degrading the effectiveness of the locking mechanism of the tie.
A novel wire bundle bounding method that meets the requirements of aerospace specifications is disclosed as well as a novel cable tie used in the method. The method starts with a bundle of wires and the cable tie. The cable tie has a strap body and a locking head with first and second strap passages. The first and second strap passages each have a pawl that locks in the same direction. The strap body is then wrapped around at least one of the wires and then inserted through the first strap passage. Then the strap body is wrapped around the bundle and then inserted through the second strap passage. The strap body is then tightened and the residual strap portion clipped.
A low profile cable tie, preferably a two-piece cable tie, has a low profile locking head with a lateral strap accepting channel and a strap preferably molded with a right angle bend that is retained in this state during non-use. The cable tie has a clean exterior appearance, including a top surface free of openings and a smooth lateral opening. With this cable tie, a strap accepting channel is provided in the locking head that is substantially parallel to a strap attachment axis. The strap accepting channel divides the locking head into a first part, which is secured to the strap, and a second part which contains a locking device. By providing the locking device on the second part, the first part can be made thinner, allowing the strap accepting channel to be closer to the cable bundle being tied. Further, in the case of a two-piece cable tie having a metal locking device, the locking device is preferably bent so as to have a fixed end substantially parallel to the strap accepting channel axis and a free end positioned within the strap accepting channel at an acute angle relative to the strap accepting channel axis. A bottom wall may be shorter in length than an upper wall to define a recessed inset that widens the effective strap accepting channel entrance without increasing the height of the locking head. The inset also allows entrance of the strap over a broader range of entrance angles.
A lightweight plastic bolt-like fastener which is used in pairs having a dual ratcheting function. The fastener includes a bolt having a stem which is semi-cylindrical in cross-section, with a head connected to one end of the stem and a semi-circular aperture in the head positioned coaxially aligned with the stem for receipt of a stem from a second bolt directed in opposite orientation. Positioned longitudinally along the flat side of the stem is a rack of serrated teeth which when the stem is inserted within the semi-circular aperture, a deflectable locking tab attached to the head end of the stem engages the rack of serrated teeth as a ratchet, and since the two fasteners each have stems sliding within the semi-circular aperture of the opposing stem, there is a double ratcheting action between both fasteners.
The fastener comprises a box or casing 6 having a tapered opening through which passes a wedge 8 having at its smaller end a projection 10 which is only slightly smaller than the opening in the casing. One end of the tie 11 is passed between the wedge and the casing and its end is turned over or other-wise secured to the casing. The other end of the tie is then inserted and the wedge, which is prefer-ably roughened on its underside, is driven in.
The endless cable tie fastener device (1) is disclosed. The device is and endless plastic strap (1) to be cut to any desired length with locking assembly (4,5) incorporated into the strap which does not protrude beyond the width of the strap. This enables the off cuts to be re-used and any desired length of cable fastening device (4,5) can be produced in a roll instead of individual single use devises.
A flexible strap, tie or filament 10 received in a fastener element 14 combined with a machine-readable marking or code 18, such as a bar code. The machine-readable marking or code may be carried by a tab or plate 16 formed integrally with the fastener element 14. Otherwise, the machine-readable marking or code may be provided on the flexible filament or strap 10. Two flexible filaments or straps 10 each fixed to a respective fastener element 14 may be used in conjunction to define a loop. This loop may then be used to secure, for example, a neck of a bag passed through the loop, by pulling pull the tabs 16 of the filaments or straps 10 in opposite directions. The filament or strap 10 may comprise ratchet teeth 12 engaged by and eye and pawl element within the fastener element. The strap, tie or filament 10 may be moulded integrally with its respective fastener element 14 and marking-carrying plate 16.
A one-piece cable tie includes a locking head and an attached strap, the locking head being adapted to receive and selectively engage a portion of the strap when the tie is formed into a closed loop. The cable tie additionally includes an insert fastener formed onto the locking head that is sized and shaped to be retained within a rectangular slot formed in a panel. The insert fastener includes a pair of spaced apart, parallel arms which extend orthogonally away from an outer end wall of the locking head, a cross-member extending transversely across the free ends of the pair of arms and a pair of offset retention fingers. Each retention finger is connected at one end to the cross-member and is capable of being independently pivotally displaced along an arcuate path. As a result of the offset design of its retention fingers, the cable tie can be manufactured as a unitary plastic member using simplified and inexpensive molding techniques.
While these tie fasteners may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
A primary object of the present invention is to provide a band fastener incorporating apparatus for releasing said fastener.
Another object of the present invention is to provide a band fastener manufactured of a polymeric or elastomeric material
Yet another object of the present invention is to provide a band fastener having serrations extending therefrom.
Still yet another object of the present invention is to provide a band fastener having a housing with a throughbore fixed at one end of said band.
An additional object of the present invention is to provide said housing with a rotative member for lockingly engaging an inserted band.
Yet another object of the present invention is to provide a band fastener wherein said housing also incorporates cutters positioned over opposing sides of an inserted band.
Still yet another object of the present invention is to provide a band fastener wherein said housing cutters are selectively engaged by depressing housing exterior portions that move the cutters into engagement with the inserted band.
Another object of the present invention is to provide a band fastener that when said cutters are moved into engagement with an inserted band, rotation of the housing rotative member with sufficient torque will sever the band at the cutter location.
Additional objects of the present invention will appear as the description proceeds.
The present invention overcomes the shortcomings of the prior art by providing a band fastener incorporating means for selectively severing the band once cinched within the housing. The band is manufactured in a polymeric or elastomeric material having serrations extending therefrom.
